Ghosts and Ghosting in Digital Communications.

Ghosting, professionally and personally, occurs when there is an abrupt end to communication between 2 individuals without any explanation or when an individual does not follow through on commitments to others associated with their communication. The increase in the available communication channels and speed at which messages can now be transmitted between individuals is resulting in a greater incidence of ghosting or perceived ghosting in our colleges/schools of pharmacy. The impact of ghosting is the disruption of effective communication and communication strategies that are essential to the development of positive and thriving cultures and subcultures in our institutions. The causes of ghosting (real or perceived) in our pharmacy academy could be attributed to increased workload and speed of communication, increased workload and productivity expectations, and increased workload and information volume. The consequences of ghosting in our colleges/schools can result in decreased psychological safety in our cultures, adversely impacting individual well-being, resiliency, grit, and satisfaction and adversely impacting student academic performance and success. There are simple steps that individuals and institutions can implement to minimize ghosting or the perception of ghosting that may occur with online communication channels used by our faculty, staff, students, and outside individuals.

Safety and Academic Outcomes of College Campus-Based Advocacy Services.

Intimate partner violence (IPV), sexual assault, and stalking are consequential public health and safety issues with wide reaching impacts on emerging adults, including those on college campuses in the United States. In response to high rates of violence among college student populations, universities are developing campus-based advocacy (CBA) programs, which aim to support survivors of interpersonal violence through supportive connections, resource acquisition, and safety planning. However, little data exists related to their impact on key student-survivor outcomes. Thus, this study aims to understand (a) the approach CBA programs use to address safety and academic concerns of student-survivors, and (b) the initial outcomes of CBA programs on safety and academics among students engaged in CBA services at five universities in one Southwestern state. The project used a longitudinal mixed-methods approach, with data collection activities including qualitative interviews with student survivors (n = 29) and a longitudinal, web-based, quantitative survey with matched analyses of safety and academic outcome measures from 115 student survivors who participated in an initial survey and follow-up survey after 6 months. Findings demonstrate key pathways through which CBA programs support survivors and facilitate positive safety and academic outcomes. These pathways include education, supportive connection, and resource access. Analysis of longitudinal survivor data demonstrate substantial reductions in sexual violence, IPV, stalking, and school sabotage at 6-month follow-up compared to initial survey, as well as significant reductions in academic disengagement for student survivors. The findings of the study powerfully demonstrate the positive impact of CBA programs on survivor and campus outcomes. Furthermore, programs not only enhance individual survivor safety and academic outcomes but also support the overall climate and safety of hosting universities.

Addressing an Uncertain Future With a Culture of Psychological Safety.

Faculty, staff, and administrators in our pharmacy colleges and schools work in well-known organizational structures that form the foundations for cultures and subcultures. The importance of promoting a positive culture and subculture is a frequent discussion in our own institutions and across the academy. However, the impact of these cultures and subcultures on individual and collective success and how they influence inclusion and innovation in our organizations are often not considered in these conversations. Psychological safety promotes an environment in an organization where an individual feels included in the culture or subculture; is safe to learn; is safe to contribute; and is safe to challenge the status quo all without the fear of being embarrassed, marginalized, or penalized in some way. Psychological safety is the foundation for enabling learning, innovation, and change in our colleges and schools of pharmacy. This commentary will highlight elements of cultures and subcultures, the importance of fostering a psychologically safe environment in our colleges and schools, and suggestions for success.

Lessons Learned from CDC's Global COVID-19 Early Warning and Response Surveillance System.

Early warning and response surveillance (EWARS) systems were widely used during the early COVID-19 response. Evaluating the effectiveness of EWARS systems is critical to ensuring global health security. We describe the Centers for Disease Control and Prevention (CDC) global COVID-19 EWARS (CDC EWARS) system and the resources CDC used to gather, manage, and analyze publicly available data during the prepandemic period. We evaluated data quality and validity by measuring reporting completeness and compared these with data from Johns Hopkins University, the European Centre for Disease Prevention and Control, and indicator-based data from the World Health Organization. CDC EWARS was integral in guiding CDC's early COVID-19 response but was labor-intensive and became less informative as case-level data decreased and the pandemic evolved. However, CDC EWARS data were similar to those reported by other organizations, confirming the validity of each system and suggesting collaboration could improve EWARS systems during future pandemics.

Academic Safety Planning: Intervening to Improve the Educational Outcomes of Collegiate Survivors of Interpersonal Violence.

Demonstrated impacts of intimate partner violence (IPV) and sexual assault (SA) for college students include negative outcomes related to mental, physical, emotional, and academic well-being. As a result of increasing awareness of the long-standing epidemic of IPV and SA on college campuses, Institutions of Higher Education (IHEs) are expanding the services provided to survivors of IPV and SA, including campus-based advocacy services that are adapted from community models. Like community advocacy, campus-based advocacy services focus on empowerment, support, resource provision, and addressing safety needs. However, the unique context of higher education produces specific student-centered needs, including an increased focus on educational goals, academic accommodations, and safety planning. The current study seeks to shed new light on the specific foci and tasks of advocacy in the context of IHEs, related to what we call "academic safety planning," and to highlight the experience of student service recipients utilizing these forms of advocacy. Thematic analysis of 48 qualitative interviews with advocates (n = 23) and service users (n = 25) from five programs at three universities was used to discover practices applied by campus-based advocates and to understand student-survivor needs and preferences within academic safety planning. Findings reveal the core components of academic safety planning, which are: (a) Advocating for emotional and physical safety in the university context, (b) Assessing and identifying needed academic accommodations, and (c) rebuilding connections and institutional trust at school. These interviews reveal that academic safety planning has the potential to enhance the academic outcomes of survivors, which in turn could lead to important improvements in long-term personal safety, well-being, and economic security for student-survivors.

Countries with delayed COVID-19 introduction - characteristics, drivers, gaps, and opportunities.

BACKGROUND: Three months after the first reported cases, COVID-19 had spread to nearly 90% of World Health Organization (WHO) member states and only 24 countries had not reported cases as of 30 March 2020. This analysis aimed to 1) assess characteristics, capability to detect and monitor COVID-19, and disease control measures in these 24 countries, 2) understand potential factors for the reported delayed COVID-19 introduction, and 3) identify gaps and opportunities for outbreak preparedness, particularly in low and middle-income countries (LMICs). We collected and analyzed publicly available information on country characteristics, COVID-19 testing, influenza surveillance, border measures, and preparedness activities in these countries. We also assessed the association between the temporal spread of COVID-19 in all countries with reported cases with globalization indicator and geographic location. RESULTS: Temporal spreading of COVID-19 was strongly associated with countries' globalization indicator and geographic location. Most of the 24 countries with delayed COVID-19 introduction were LMICs; 88% were small island or landlocked developing countries. As of 30 March 2020, only 38% of these countries reported in-country COVID-19 testing capability, and 71% reported conducting influenza surveillance during the past year. All had implemented two or more border measures, (e.g., travel restrictions and border closures) and multiple preparedness activities (e.g., national preparedness plans and school closing). CONCLUSIONS: Limited testing capacity suggests that most of the 24 delayed countries may have lacked the capability to detect and identify cases early through sentinel and case-based surveillance. Low global connectedness, geographic isolation, and border measures were common among these countries and may have contributed to the delayed introduction of COVID-19 into these countries. This paper contributes to identifying opportunities for pandemic preparedness, such as increasing disease detection, surveillance, and international collaborations. As the global situation continues to evolve, it is essential for countries to improve and prioritize their capacities to rapidly prevent, detect, and respond, not only for COVID-19, but also for future outbreaks.

Do seedlings of larger geophytic species outperform smaller ones when challenged by drought?

PREMISE: In semiarid regions, decreasing rainfall presents a challenge to perennial seedlings that must reach sufficient size to survive the first year's seasonal drought. Attaining a large storage organ size has been hypothesized to enhance drought resilience in geophytes, but building larger storage organs requires faster growth, but paradoxically, some traits that confer faster growth are highly sensitive to drought. We examined whether tuber size confers greater drought resilience in seedlings of four closely related geophytic species of Pelargonium. METHODS: We imposed two drought treatments when seedlings were 2 months old: chronic low water and acute water restriction for 10 days. Plants in the acute dry-down treatment were then rewatered at control levels. We compared morphological and ecophysiological traits at 2, 3, and 6 months of age and used mixed-effects models to identify traits determining tuber biomass at dormancy. RESULTS: Despite a 10-fold variation in size, species had similar physiological trait values under well-watered conditions. Chronic and acute droughts negatively affected tuber size at the end of the season, but only in the two species with large tubers. Chronic drought did not affect physiological traits of any species, but in response to acute drought, larger species showed reduced photosynthetic performance. Canopy area was the best predictor of final tuber biomass. CONCLUSIONS: Contradictory to the hypothesis that large tubers provide greater drought resiliency, small Pelargonium seedlings actually had higher drought tolerance, although at the expense of more vigorous growth compared to species with larger tubers under well-watered conditions.

Natural history in spinal muscular atrophy Type I in Taiwanese population: A longitudinal study.

INTRODUCTION: Spinal muscular atrophy (SMA) is caused by a defect in the survival motor neuron 1 (SMN1) gene. The Cooperative Study of the natural history of SMA Type I in Taiwan is a retrospective, longitudinal, observational study that helps in further understanding SMA disease progression in patients who have not received disease-modifying therapeutic interventions. METHODS: Case report forms were used to collect demographics; genetic confirmation; SMN2 copy number; treatment patterns; and clinical outcomes including ventilator use, endotracheal tube intubation, tracheostomy, gastrostomy, complications, and survival. RESULTS: A total of 111 patients with SMA Type I were identified over the study period (1979-2015). Mean (median) age of onset and age at confirmed diagnosis were 1.3 (0.8) and 4.9 (4.4) months, respectively. SMN1 deletion/mutation was documented in 70 patients and SMN2 copy number in 32 (2 copies, n = 20; 3 copies, n = 12). At 240 months, survival probability for patients born during 1995-2015 versus 1979-1994 was significantly longer (p = 0.0057). Patients with 3 SMN2 copies showed substantially longer 240-month survival versus patients with 2 SMN2 copies. Over the 36-year period, mean (median) age at death was 31.9 (8.8) months. As of December 2015, 95 patients had died, 13 were alive, and 3 were lost to follow-up. The use of supportive measures (tracheostomy and gastrostomy) was associated with improved survival. CONCLUSIONS: These data describe the short survival of patients with SMA Type I in Taiwan in the pretreatment era, emphasizing the positive impact of supportive measures on survival.

Exploring Dendrimer Nanoparticles for Chronic Wound Healing.

The United States spends billions of dollars to treat chronic wounds each year. Wound healing is complex in nature which involves several intricate multiphase processes that can be delayed for a number of reasons leading to the development of chronic wounds. Wound healing therapies range from topical preparations to surgical repair with treatment options that vary based on other underlying factors like co-infection, age, or co-morbidities such as diabetes. Historically, micelles and liposomes are some of the nanoparticle drug delivery systems explored to treat chronic wounds; however, recent data suggests that dendrimers have shown potential to rival these systems in treating chronic wounds as well as other diseases. This mini review examines advances in dendrimer nanoparticle drug delivery systems to treat chronic wounds.

The Cure SMA Membership Surveys: Highlights of Key Demographic and Clinical Characteristics of Individuals with Spinal Muscular Atrophy.

BACKGROUND: Cure SMA maintains the largest patient-reported database for people affected with spinal muscular atrophy (SMA). In 2017, Cure SMA initiated annual surveys with their membership to collect demographic and disease characteristics, healthcare, and burden of disease information from patients and caregivers. OBJECTIVE: To summarize results from two large-scale Cure SMA surveys in 2017 and 2018. METHODS: Cure SMA database members were invited to complete surveys; these were completed by caregivers for living or deceased individuals with SMA and/or affected adults. RESULTS: In 2017, 726 surveys were completed for 695 individuals with SMA; in 2018, 796 surveys were completed for 760 individuals with SMA. Data from both survey years are available for 313 affected individuals. Age at symptom onset, distribution of SMN2 gene copy number, and representation of each SMA type in the surveys were consistent with that expected in the SMA population. In the 2018 survey, the average age at diagnosis was 5.2 months for SMA type I and the reported mean age at death for this subgroup was 27.8 months. Between survey years, there was consistency in responses for factors that should not change within individuals over time (e.g., reported age at diagnosis). CONCLUSIONS: Results from the Cure SMA surveys advance the understanding of SMA and facilitate advocacy efforts and healthcare services planning. Longitudinal surveys are important for evaluating the impact of effective treatments on changing phenotypes, and burden of disease and care in individuals with SMA.

The implementation of a dedicated education unit in a public health setting.

INTRODUCTION: The dedicated education unit (DEU) is an innovative clinical model that prepares preceptors for success in clinical settings with nursing students. Though the DEU is mostly used in acute-care settings, this project explores the implementation of a DEU in a public health setting. OBJECTIVES: Better preparation of public health nurses and social workers as clinical preceptors for nursing students with the implementation of a DEU in a public health setting. DESIGN: IRB approved, pre/post survey with participant comments. MEASUREMENTS: Clinical Nurse Teacher Survey was assessed pre/post intervention with registered nurses and social work staff (n = 13). Paired t-tests analysis was used to determine significance. The Clinical Learning Environment and Nurse Teacher (CLES+T) scale completed postimplementation by nursing students (n = 8) after the clinical rotation. RESULTS: Clinical Nurse Teacher Survey mean scores preintervention was 4.56 and increased postintervention to 4.89, though not statistically significant (p-value .11). CLES+T showing 100% fully agree or agree that the Public Health DEU is an effective learning environment. CONCLUSIONS: The DEU model in a public health setting is an opportunity to improve lived clinical experiences of preceptors and nursing students, which may increase nursing students' positive perceptions of, and increase interest in serving as a public health nurse after graduation.

Observations of the global epidemiology of COVID-19 from the prepandemic period using web-based surveillance: a cross-sectional analysis.

Background Scant data are available about global patterns of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread and global epidemiology of early confirmed cases of COVID-19 outside mainland China. We describe the global spread of SARS-CoV-2 and characteristics of COVID-19 cases and clusters before the characterisation of COVID-19 as a pandemic. METHODS: Cases of COVID-19 reported between Dec 31, 2019, and March 10, 2020 (ie, the prepandemic period), were identified daily from official websites, press releases, press conference transcripts, and social media feeds of national ministries of health or other government agencies. Case characteristics, travel history, and exposures to other cases were abstracted. Countries with at least one case were classified as affected. Early cases were defined as those among the first 100 cases reported from each country. Later cases were defined as those after the first 100 cases. We analysed reported travel to affected countries among the first case reported from each country outside mainland China, demographic and exposure characteristics among cases with age or sex information, and cluster frequencies and sizes by transmission settings. FINDINGS: Among the first case reported from each of 99 affected countries outside of mainland China, 75 (76%) had recent travel to affected countries; 60 (61%) had travelled to China, Italy, or Iran. Among 1200 cases with age or sex information, 874 (73%) were early cases. Among 762 early cases with age information, the median age was 51 years (IQR 35-63); 25 (3%) of 762 early cases occurred in children younger than 18 years. Overall, 21 (2%) of 1200 cases were in health-care workers and none were in pregnant women. 101 clusters were identified, of which the most commonly identified transmission setting was households (76 [75%]; mean 2·6 cases per cluster [range 2-7]), followed by non-health-care occupational settings (14 [14%]; mean 4·3 cases per cluster [2-14]), and community gatherings (11 [11%]; mean 14·2 cases per cluster [4-36]). INTERPRETATION: Cases with travel links to China, Italy, or Iran accounted for almost two-thirds of the first reported COVID-19 cases from affected countries. Among cases with age information available, most were among adults aged 18 years and older. Although there were many clusters of household transmission among early cases, clusters in occupational or community settings tended to be larger, supporting a possible role for physical distancing to slow the progression of SARS-CoV-2 spread. FUNDING: None.

Effect of bile duct ligation-induced liver dysfunction on methamphetamine pharmacokinetics in male and female rats.

BACKGROUND: Several disease states commonly associated with methamphetamine (METH) use produce liver dysfunction, and in the bile duct ligation (BDL) model of hepatic dysfunction, rats with liver injury are more sensitive to METH effects. Additionally, both female rats and humans are known to be more sensitive to METH than males. In consideration of known sex-dependent differences in METH pharmacokinetics, this study sought to determine the potential interaction between sex and liver dysfunction variables on METH pharmacokinetics. METHODS: Sham or BDL surgery was performed on male and female rats on day 0. Serum biomarker and pharmacokinetics studies with 3 mg/kg subcutaneous (SC) METH were performed on day 7. METH-induced weight loss was measured on day 8. Liver histology evaluation and brain METH concentration measurements were performed on day 9. RESULTS: While BDL surgery produced significantly elevated alanine aminotransferase and bile duct proliferation in male compared to female rats, there were no significant interactions between sex and liver function in the pharmacokinetic parameters. Both liver dysfunction and female sex, however, were associated with significantly slower METH serum clearance and significantly higher brain METH concentrations (p < .05). CONCLUSIONS: BDL-induced hepatic dysfunction produces substantial reductions in METH clearance and increased brain METH concentrations in both male and female rats, despite less liver injury in females. This preclinical model may be useful to identify and correct potential liver dysfunction comorbidity-related problems with future pharmacotherapy for stimulant use disorder with METH prior to expensive clinical trials.

Leaf margins in a deciduous lineage from the Greater Cape Floristic Region track climate in unexpected directions.

PREMISE: The functional significance of leaf margins has long been debated. In this study, we explore influences of climate, leaf lobing, woodiness, and shared evolutionary history on two leaf margin traits within the genus Pelargonium. METHODS: Leaves from 454 populations of Pelargonium (161 species) were collected in the Greater Cape Floristic Region and scored for tooth presence/absence and degree of lobing. Tooth density (number of teeth per interior perimeter distance) was calculated for a subset of these. We compared five hypotheses to explain tooth presence and density using mixed effect models. RESULTS: Tooth presence/absence was best predicted by the interaction of leaf lobing and mean annual temperature (MAT), but often in patterns opposite those previously reported: species were more likely to be toothed with warmer temperatures, particularly for unlobed and highly lobed leaves. In contrast, tooth density was best predicted by the interaction of MAT and the season of most rain; density declines with temperature as consistent with expectations, but only in winter-rain dominated areas. Woody and nonwoody species within Pelargonium have similar associations between tooth presence/absence and MAT, contrary to the expectation that patterns within nonwoody species would be insignificant. CONCLUSIONS: We conclude Pelargonium leaf margins show predictable responses to climate, but these responses are complex and can contradict those found for global patterns across plant communities.

Real-World Safety and Effectiveness of Dimethyl Fumarate in Hispanic or Latino Patients with Multiple Sclerosis: 3-Year Results from ESTEEM.

INTRODUCTION: Compared with the non-Hispanic/non-Latino population, Hispanic/Latino patients with multiple sclerosis (MS) are reported to exhibit greater disease severity. Geographical location and genetics play a role in differences observed across Hispanic/Latino subpopulations. We evaluated real-world safety and effectiveness of dimethyl fumarate (DMF) on MS disease activity in Hispanic/Latino patients. METHODS: ESTEEM is an ongoing, 5-year, multinational, prospective study evaluating long-term safety and effectiveness of DMF in patients with MS. This interim analysis included patients newly prescribed DMF in routine practice at 394 sites globally. RESULTS: Overall, 4986 non-Hispanic/non-Latino and 98 Hispanic/Latino patients were analyzed; median (range) follow-up was 18 (2-37) months. Unadjusted annualized relapse rates (ARRs) for 12 months before DMF initiation versus 36 months post DMF initiation, respectively, were: non-Hispanic/non-Latino patients, 0.82 (95% CI 0.80-0.84) versus 0.10 (95% CI 0.09-0.10), 88% lower ARR (P < 0.0001); Hispanic/Latino patients, 0.80 (95% CI 0.65-1.00) versus 0.09 (95% CI 0.06-0.14), 89% lower ARR (P < 0.0001). In total, 28 (29%) Hispanic/Latino patients reported adverse events leading to treatment discontinuation; gastrointestinal (GI) disorders (n = 10, 10%) were the most common, consistent with the non-Hispanic/non-Latino population (8%). Median lymphocyte counts decreased by approximately 24% in the first year (vs 36% decrease in non-Hispanic/non-Latino patients) then remained stable and above the lower limit of normal in most patients. CONCLUSIONS: Relapse rates remained low in Hispanic/Latino patients, consistent with non-Hispanic/non-Latino patients. The safety profile of DMF in Hispanic/Latino patients was consistent with safety findings from the non-Hispanic/non-Latino ESTEEM population, demonstrating the real-world treatment benefit of DMF in the Hispanic/Latino patient cohort.

Real-World Safety and Effectiveness of Dimethyl Fumarate in Black or African American Patients with Multiple Sclerosis: 3-Year Results from ESTEEM.

INTRODUCTION: Black or African American (black/AA) patients with multiple sclerosis (MS) are reported to exhibit greater disease severity compared with non-black or non-AA patients. Whether differences exist in response to MS disease-modifying therapies remains uncertain, as MS clinical trials have included low numbers of non-white patients. We evaluated real-world safety and effectiveness of dimethyl fumarate (DMF) on MS disease activity in black/AA patients. METHODS: ESTEEM is an ongoing, 5-year, multinational, prospective study evaluating long-term safety and effectiveness of DMF in patients with MS. This interim analysis included patients newly prescribed DMF in routine practice at 394 sites globally. RESULTS: Overall, 4897 non-black/non-AA and 187 black/AA patients were analyzed; median (range) follow-up 18 (2-37) months. Unadjusted annualized relapse rates (ARRs) for 12 months before DMF initiation versus 36 months post DMF initiation, respectively, were: non-black/non-AA patients, 0.83 (95% CI 0.80-0.85) versus 0.10 (95% CI 0.09-0.10), 88% lower ARR (P < 0.0001); black/AA patients, 0.68 (95% CI 0.58-0.80) versus 0.07 (95% CI 0.05-0.10), 90% lower ARR (P < 0.0001). In total, 35 (19%) black/AA patients reported adverse events leading to treatment discontinuation; gastrointestinal disorders were most common (7%), consistent with non-black/non-AA patients (8%). Median lymphocyte counts decreased by 22% in the first year (vs 36% in non-black/non-AA patients), then remained stable and above lower limit of normal in most patients. CONCLUSIONS: Relapse rates remained low in black/AA patients, consistent with non-black/non-AA patients. The safety profile of DMF in black/AA patients was consistent with that in the non-black/non-AA ESTEEM population, although lymphocyte decrease was less pronounced in black/AA patients.

Spinal Muscular Atrophy (SMA) Subtype Concordance in Siblings: Findings From the Cure SMA Cohort.

BACKGROUND: Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by homozygous survival of motor neuron 1 (SMN1) gene disruption. Despite a genetic etiology, little is known about subtype concordance among siblings. OBJECTIVE: To investigate subtype concordance among siblings with SMA. METHODS: Cure SMA maintains a database of newly diagnosed patients with SMA, which was utilized for this research. RESULTS: Among 303 sibships identified between 1996 and 2016, 84.8% were subtype concordant. Of concordant sibships, subtype distribution was as follows: Type I, 54.5%; Type II, 31.9%; Type III, 13.2%; Type IV, 0.4%. Subtype and concordance/discordance association was significant (Fisher's exact test; p < 0.0001). Among discordant sibships (chi-square test, p < 0.0001), Types II/III (52.2%) and Types I/II (28.3%) were the most common pairs. No association was found between sibling sex and concordance. Our findings show that most siblings with SMA shared the same subtype concordance (most commonly Type I). CONCLUSIONS: These data are valuable for understanding familial occurrence of SMA subtypes, enabling better individual treatment and management planning in view of new treatment options and newborn screening initiatives.
